ivrrn sa TRANSOM-PIVOT Original application filed January 11, 1909, Serial No. 471,692. Divided and this application filed March 8, 1909.

Serial No.

To all whom it may concern:

Be it known that l, JOHN H. GILMAN, a citizen of the United States, residing at Kalamazoo, Kalamazoo county, Michigan, have invented certain new and useful Improvements in Transom-Fivots, of which the fol` lowing is a specification.

This invention relates to improvements in pivots for transoms, windows and the like.

The main object of this invention is to provide an improvedpivot for transoms, piv` oted windows and the like which enables the easy setting or placing of the transom or window, which is practically invisible in use.

Another object is to provide an improved pivot for transoms, windows or the like, which is comparatively simple and economical in structure.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

accomplish the objects of my invention by the devices and means described in the following speciiication.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure i is a detail elevation of a structure embodying the features of my invention, portions being shown in section and portions being broken away to show the form and the arrangement of the parts. Fig. 2 is a vertical section, taken on line 2 2 of Fig. l. Fig. 3 is an edge view of the window or transom with the socket bearing 13 seated therein. Fig. i is a side elevation of the cross piece S with operating cords attached thereto. Fig. 5 is a detail view, taken on a line corresponding to line 5 5 of Fig. 1, showing the socket member 6.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawing, the casing l is of the usual construction of door or window casing, the transom or window 2 being pivoted in the casing. The pivot 3 is provided with a rectangular head 4 to engage the rectangular socket 5 in the plate 6, so that the window is swung as the pivot is turned.

Specification of Letters Patent.

' Patented July 27', i909.

The pivot is mounted in a bearing 7, which is seated in the casing, the pivot being arranged therethrough and being provided with a cross piece 8 at its inner end. The operating cords 9 are attached to the ends of the cross piece, the cords being preferably operated through the :mechanism illustrated in my application for Letters Patent filed January Il, 1,909, Serial No. 471,692, of which this is a divisional application. The cross piece 8 is preferably secured upon the pivot 3 by means of a nut, as l0, so that the pivot can be arranged through its bearing from the outside and the cross piece secured thereon. ing plate are preferably countersunk into the window and the i casing, `rrespectively, and secured by means of thescrews, as 11, so that a tight fit can be had between the window and the casing.

To provide means for the easy insertion of the window into the casing, I preferably provide the pivot l2 with means for shifting it longitudinally so that the transom or window can be inserted and the pivot shifted longitudinally to engage the pivot socket 13 which is countersunk into the frame, as clearly appears in Fig. l. To accomplish this longitudinal shifting, the 'pivot i2 is arranged in a support 14, which is provided with a socket in which the pivot may be lone gitudinally adjusted. The pivot is provided ith rack teeth 16, the same being preferably in the form of annular ribs. An adjusting worm i7 is provided for the rack member i8, which is ivoted at 19 in the slot-like aperture 2O o the support 14.-. The worin 17 has a screw head 2i which is engaged with a screw driver for adjusting the pivot. The worm is retained in the support by riveting its inner end, as at 22, upon the washer 23. By this arrangement, the pivot can be withdrawn to permit the removal of the window or transom; or, in .inserting the transom, the transom is put in place and the pivot is proj eeted into the socket i3 through the adjusting worm i7. The support 11i is seated in the casing so that the window may be fitted very accurately to the casing and at the same time is readily and quickly adjusted.

My improved pivot is comparatively simple and economical in structure, and, at the same time, is very convenient and practical in use.

have illustrated and described my im- The socket plate 6 and the bear-4 pable of considerable variation in structural details .Without departing from my inven. tion; but, as these modifications Will `be` *readily comprehended by -t`hose skilled in the art to which this invention relates, il haye not attempted to illustrate or describe the 'p -sa-me herein.

Haw/'ing thus described any invention, what I -c'laim as inew and desire 'to;secure :by Letters Patent isf:

l. The :combination .Wit'h .-a pivot having ;a rack thereon.; 'a pivot support, said `:support ehaving za socket 4in which said zpivot fis 1longiatudinally adjustable; an adjusting worm ro- .etatably mountedinzsaidsupport; and .a rack member pi-voted in :said `support to engage said pivot andsaidadjfusting worm, said support having a `slot-.like :aperture 'to receive y-said Tack member.

a'otatably mounted lin said support; yand a rack member pivoted in said su port to engage said ipivot .and .said adjusting Worm.

'3. IThe combination With a pivot having a rack thereon, of a support in Which said vpivot is longitudinally adjustable; a pivoted rack member arranged in said su .port toengage said pivot; and means for s lifting said rack member.

4. FThe combination with a pivot, of a suport in Which said pivot is longitudinally adjustable; an .adjusting Worm rotatably mounted in said support; and fconnections .forsaid -worm and fpivozt Whereby said. pivot may be Ashifted :longitudinally ,through :the lmanipulation of said Worm.

5. vThe :combination with a pivot having annular ribs forming a rack thereon, of :a vsupport in which said `pivot is longitudinally adjustable; .and a yrack member lpivoted in said support to engage the 'rack'o'i -said pivot.

'In VWitness whereof, l have hereunto set my hand .and seal -inithe fpresenceioll two Wit* nesses.
